Inventor: TAKAHASHI HIDEO
IPC: C25D3/30
Filed: 1978-12-05
Abstract: PURPOSE: To correctly control the alloy amount on the plated metal plate by calculating the ultimate heating temperature and formed alloy amount in resistance heating and induction heating, obtained deviation-elimination-corresponding voltage from the alloy amount thus calculated and a preset alloy amount and determining control voltage then inputting the same to the control system for both heating.  
     CONSTITUTION: At the time of heat treating the metal plate having been plated with dissimilar metals through combination of resistance heating and induction heating, the intermediate point temperature of the point corresponding to the mean value of electric resistivities and the ultimate temperature in the heating zone are calculated from the voltage, current, line speed, dimensions and material of the metal plate, plating amount and atmospheric temperature in resistance heating and further the ultimate temperature in induction heating is also calculated. From the ultimate temperatures of both, the formed alloy amount is calculated and the deviation-elimination-corresponding voltage for the set alloy amount is obtained. Thence, a control voltage is determined from the line speed, the intermediate point temperature of the resistance heating and the corresponding voltage, and is then inputted to the control system of the heating device, whereby the controlling of the alloy amount is accomplished.

Title: Cryopump, regenerating method and device for cryopump, and method of controlling cryopump
Inventor: KITA YUICHI
IPC: F04B37/16
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To make a cryopump quickly open an exhaust valve when the internal pressure of the pump reaches a specified level a little higher than the atmospheric pressure. SOLUTION: An exhaust valve 35 is formed out of a solenoid valve and includes a regeneration controller 41. The controller 41 opens the valve 35 to discharge the process gas when, at the time of reprocessing, the internal pressure of a casing 33 based on a pressure signal given from a pressure sensor 37 attains a specified level set some higher than the atmospheric pressure. At the attainment of the specified level, the regeneration gas (process gas) is exhausted immediately so as to avoid explosion of the hydrogen gas produced by a dislocation of the exhaust timing, breakage of a gate valve, counter-flow of the open air, etc., and thus a safe and accurate regenerative processing is established.

Title: X-ray stress measuring device
Inventor: KAMINAGA UKYO
IPC: G01L1/00
Filed: 1984-07-23
Abstract: PURPOSE:To measure internal stress by turning one of X-ray sources which irradiate a sample and a measurement point with X-ray beams in the same direction with a detection part at an angular speed with it or in the opposite direction at the same angular speed. CONSTITUTION:If some of diffracted X rays 71-7n is generated at the measurement point 3 of the sample when an X-ray beam 5 is made incident on the measurement point 3 from an X-ray tube S, the diffracted X rays are detected D1-Dn and stored in storage devices M1-Mn. The crystal lattice surface of the sample 1 which generate the diffracted X rays is at right angles to the bisector between the beam 5 and one of the X rays 71-7n, but a detector base H and the X-ray tube S move at the same speed in the opposite directions, so bisectors are held unchanged in position. The position of the diffracted rays of the crystal lattice surface perpendicular to each bisector is therefore known from the outputs of respective detectors D1-Dn. Relations between intensity variations and scanning positions of those diffracted rays 7 are stored in the storage devices M1- Mn, so internal stress is calculated from the scanning position where each diffracted rays are maximum.

Abstract: PURPOSE:To obtain a toner image having low fogging and large contrast and excellent in developing and transfer efficiency by using toner having a specific dielectric constant and a specific dielectric loss tangent and impressing bias voltage between a positive electric charge image supporting carrier and a developing sleeve to execute development. CONSTITUTION:The toner having 2.5-3.5, especially 2.7-3.1, dielectric constant and 2.5 X 10<-3>-6.0 X 10<-3> dielectric loss tangent (tag delta) measured by using 100kHz frequency is used as the toner and bias voltage corresponding to 15-60% the surface potential of the carrier is impressed between the positive charge image supporting carrier and the developing sleeve to execute develop ment. Since a fixed restriction exists in the dielectric constant (epsilon) of toner, the value is regulated within the range of 2.5-3.5, especially 2.7-3.1. When the dielectric loss tangent is larger than the range, the toner charge is reduced, so that fogging is easily generated at the time of development, and when the dielectric loss tangent is smaller, image density is dropped. When the developing bias voltage (VB) is low, there is no effect to the prevention of fogging, and in case of high bias voltage, the potential contrast VS-VB of an image part can not be sufficiently increased.

Title: Static circuit breaker
Inventor: OZAKI MASA
IPC: H02H3/08
Filed: 1987-06-18
Abstract: PURPOSE:To permit a tripping device to surely perform its breaking action even when a rated breaking current is increased, by providing a limiting circuit, which connects a limiting resistor element and a magnetism detecting switch is series, in parallel with a converting resistor element which converts an output current in a current transformer into output voltage. CONSTITUTION:When an electric current decreases in a main circuit, output resistance becomes a resistance value R1 of a converting resistor element 15. When the electric current increases in the main circuit, the action of magnetic force generated by a conductor 6 closes a magnetism detecting switch 23, thus connecting the converting resistor element 15 and a limiting resistor element in parallel. The output resistance R becomes a parallel connected resultant resistance value R1.R2/(R1+R2) resulting from the resistance value R1 of the converting resistor element 15 and the resistance value R2 of the limiting resistor element 22. Accordingly, the parallel connected resultant resistance value decreases below the resistance value R1, and output voltage is limited. In this way, a tripping device 19 is enabled to surely perform its breaking action without being placed in an attractive action area.
